Weasel Wednesday

Oct26

Sometimes when you go birding you don’t find what you hope to see.  But sometimes you see something unexpected that is just as great.  And sometimes it’s not even a bird.

Last Saturday the Friends of Fish Creek Society birders explored the Votier’s Flats area of Fish Creek Park.  Our goal was to find a Northern Pygmy-Owl, which is always a treat to see, and which several members of the group had never seen.  The owl has not yet been reported in the park this fall but in the last few years it has first been sighted at about this time.

We didn’t find an owl, but someone spotted a writhing mass at the side of the path that turned out to be a family of Least Weasels – a mother with eight young.

The nine little mammals moved through the undergrowth in a mass, over and under each other, but always in contact.  In his report on Albertabird, Gus Yaki described them as “travelling together so close that they seemed to be a single organism.”  Pat Bumstead says that they probably were making one of their first forays outside their natal den, and were exploring their surroundings.

The mother crossed the trail near us, and the young separated amongst our feet.  They showed no fear of us.  I put my hand down, and briefly had one in my gloved hand.  The shots below show just how small Least Weasels are.  These young are as big as an adult, or nearly so.

The juveniles eventually crossed the trail to reunite with their mother.

Although they are impossibly cute, weasels are carnivores, capable of killing animals many times their size.  In these photos they show off their teeth.

We were very lucky to see such an amazing sight.  If you’re like me, you can’t get enough of looking at these little guys, so below there are some more pictures for you to enjoy.

Brand New Downies

Oct25

We recently had a couple of very cute visitors to the yard – a couple of hatch year downy woodpeckers. They seemed to be eagerly checking out their surroundings, much like excited youngsters of any species in a new environment.  They were so small that when the first one landed on the tree, I thought for a minute it was a Brown-creeper.

Nothing But Shoreline

Oct24

The irrigation canal in southeast Calgary is drained in late September, and as the water level drops, it exposes lush shorelines with plenty for the birds to eat.  From mid-September to freeze-up is the time to get out to look for waterfowl, gulls, and late migrating shorebirds.

Fall colours reflected in the remaining water

I usually explore the sections from the canal headworks near the Max Bell Arena to south of 50 Avenue SE.  There are four parking areas, and you can go up and down a portion of the canal from each one.  It’s a long walk to do it all at once, but a fairly short bike ride.

Click to enlarge the map.

Max Bell Arena:  Access from Barlow Trail SE, just south of Memorial Drive.  There is a large parking lot north of the arena, and you can walk down to the canal headworks from there, and walk along the east bank.  If you want to get to the west bank, you have to cross over at the 17 Avenue SE bridge.

Bow Waters Canoe Club:   Access is off 26 Street SE, just south of 17 Avenue.  Cross the bridge to get to the paths on the west side.  The path on the east side between here and Gosling Way has some steep, difficult terrain, and it is almost impassable by bike.  This lot is fairly secluded and I don’t like to leave my vehicle there.  I prefer Max Bell or Gosling Way.

Gosling Way:  Go west off 26 Street SE at 34 Avenue.  This is the road that goes to the Inglewood Golf and Curling Club.  The parking lot, used by off-leash dog walkers, is just west of the bridge over Deerfoot trail, on the south side of Gosling Way.  It only holds about ten vehicles.  From this lot, walk down to the bridge over the canal and take the paths from there.  In the winter, you can also park at the golf and curling club, but it is a bit of a walk back to the canal.

50 Avenue SE:  It is difficult to park here.  There are only two small spots, each with room for two cars,  at the east end of the bridge over the canal.  It can also be a very busy road, so I avoid parking here as well, and usually just walk from Gosling Way.

The canal has a paved path on one side (sometimes on the east, sometimes on the west) and a dirt or gravel path of sorts on the other side.  I like to go on the east side in the mornings and on the west side in the afternoons, to keep the sun behind me.  This late in the year, the water is usually frozen in the mornings, so there are few birds around.  But on warm afternoons the ice melts, and the birds arrive.

Pat and I have each posted about birding the canal before.  You can see Pat’s post here, and my post here.

Lately I’ve seen quite a few Canada Geese, Mallards, and Ring-billed Gulls, and a few Hooded Mergansers, Common Goldeneyes, and Greater Yellowlegs.  In past years I’ve seen Redheads, Blue-winged Teal, Killdeer, Long-billed Dowitchers, and Rusty Blackbirds all feeding along the shorelines.

Sunday Showcase: Young Swainson’s Hawk

Oct23

Rob English was fortunate enough to capture these stunning shots of a young Swainson’s hawk hunting grasshoppers. He took them in Hulls’ Wood, Fish Creek Park in early September. He says the bird hung around the area for about three days, and showed no fear. His wife named him “Mr. Personality.” Thanks so much for sharing these Rob! Click to enlarge. 

eBird

Oct22

“Global tools for birders, critical data science”.

This one line sums up eBird perfectly. eBird is an online checklist program for birders that has changed the way we submit and access data for the better. This program enables you to easily view data submitted from across the globe by birdwatchers.

Well how does it work? eBird gets many thousands of birders engaged in contributing to a huge online database. You simply fill in a checklist on your birding trip; the who, what, when and where of the outing and then submit the form. eBird stores the data and allows you to view your own lists of what you have seen for the month, for the year, for a certain location and so on. Rare birds get flagged by the data quality filters and are then reviewed by local experts. Once a rare bird has been confirmed it is accessible for all to see via rare bird alerts, allowing others to share in the discovery. Your checklist goes to the database to help scientists accumulate information on birds and helps them to determine species ranges, bird distribution and other such data which can help save endangered birds. As they explain on the website: “any contribution made to eBird increases our understanding of the distribution, richness, and uniqueness of the biodiversity of our planet.” I look forward to seeing many observations submitted to eBird from you!

A Bird ID Quiz

Oct21

We received the following email from a birder in the United Kingdom, and asked him if we could post it on our blog. He’s looking  for ID help on three local bird species, so we thought we would ask our readers what they think the birds are. Two sparrow-ish birds and a shorebird should give you quite a challenge. Leave your best guesses in the comments below, and we’ll put up the correct answers eventually…

Dear Pat, Bob and Matthew,

Firstly I want to say how great your blog is – I have just gotten back to the UK after two weeks in your neck of the woods [late September] and the blog was very helpful in finding out about local spots and unfamiliar birds! I particularly enjoyed the sections on Fish Creek Park which we visited a couple of times and had great views of Bald Eagle, fishing Osprey and Lesser Yellowlegs.

I have a couple of ID questions that I hope you can help me solve! This was my first trip to Canada and most of the species are entirely unfamiliar (I have just one short non-birding trip to Texas last year as previous North American experience!).

Firstly, I attach a jpg file, ‘Sparrow sp’. I intially thought this was a pipit from stance but later revised my opionion to a sparrow, possibly Vesper due to the strong white eye ring. It was foraging for food in sparsely vegetated ground near the Elbow Valley constructed wetland. Any thoughts on ID would be greatly appreciated!

Another,  ‘Bunting sp’ is also attached… This one was seen out near Forgetmenot Pond by the Elbow River. I’m thinking Lapland Longspur but wouldn’t be surprised to discover it’s something else!

Finally, a picture of a Yellowlegs from Fish Creek Park near Mallard Point. I initially thought it was a Lesser, but the bill length, amount of yellow on the bill base and the head shape have made me unsure, although it lacks the bolder streaking of Greater. Your views are appreciated.

Many thanks in advance for your time and assistance, and with great appreciation for your blog,

Steve Marshall

95+ Years of Pigeon Roosts

Oct18

If you’ve ever driven south on Deerfoot Trail, you would have passed the Federal Grain Elevator in Bonnybrook, on the west side of the road.

This grain terminal was built around 1916, and over the years, has provided roosting and nesting sites for untold thousands of rock doves. When the grain trucks were delivering to the building on a daily basis, the spilled grain also attracted ducks and geese from the nearby Bow River. All that terrestrial bird activity naturally attracted the predators, and it was often a good place to spot a Northern Goshawk in the winter.

As of last Sunday, the rock doves have lost their perch. Apparently the high cost of operating the aging structure meant it was no longer financially advisable, so it was imploded at 8:00 am Sunday morning.

On a chilly pre-dawn morning, we were lined up on the hill to the west of the elevator with the media, police and a host of spectators. I was there because I was curious about the bird aspect of the whole thing.

The charges were set mid-way down the building, so when it went down, the rock doves on the roof went up. They circled the area, drifting in and out of the large dust cloud as it wafted towards the east.

The explosion also lifted a flock of geese off the river, and a small flock of ducks.

The whole thing was over in less than two minutes. As the sun rose through the dust, the rock doves gradually settled on a small, remaining tower, no doubt wondering what on earth had just happened to their world.
